Sany Original Air Conditioning Expansion Valve 447500-2750, Sany Material Code: 60153197, suitable for multiple models.

Original Air Conditioning Expansion Valve 447500-2750, Sany Material Code: 60153197, suitable for multiple models.
- Material Code: 60153197
- Denso Model: 447500-2750 (Original Denso Part)
- Functional Positioning: Core throttling component of the air conditioning refrigeration system. It controls the flow of refrigerant, enabling the transformation from high-pressure liquid to low-pressure mist state, ensuring the cooling effect of the evaporator.
- Compatible Models: Sany SY Series Excavators (SY335/SY365/SY375/SY385 and other Denso air conditioning models), also compatible with some same-specification Denso air conditioning equipment.
- Material Structure: Aluminum valve body + copper temperature sensing bulb, corrosion-resistant and high-pressure resistant, suitable for harsh working conditions of engineering machinery.
- Fault Symptoms: Blockage or failure of the expansion valve will lead to no cooling, frosting on the low-pressure pipe, poor cooling effect, or intermittent cooling.
- Installation Notes: When replacing, the dryer bottle should be replaced simultaneously. Vacuum the system and add sufficient refrigerant to avoid secondary blockage caused by impurities entering the system.
